My commit at the end of the last weekend in October 2013.

I added form validation and error handling, a new jet class, a new airport class. I also put in a function for calculating the distance between airports.
End of Halloween

My commit at the end of Halloween. I struggled with Foreign key
references. When filtering by foreign key fields you need to specify
what attribute (by default it is the ID) you are querying.

I also had to change the get_values() function for Flights because of
the Foreign Keys.

I made USD the default currency for the app.
My commit on Saturday night. I did several things:

I fixed the currency display and handling.

I set up the website flow more or less how I want it.

I make the forms interact how I want them two, including a separate form for searching on the current results.
if the database is to be accessed out of the admin site, the full path needs to be added to DATABASE, NAME: in settings.py

I added jetpicture model so that multiple pictures can be added to a jet

I updated fields in the Aiport model

I updated the airport model database with all 7000+ airports, got a pretty well sturctured database from http://www.halfgaar.net/localized-world-airport-codes

I put in search capabilities in the admin site
